Application filed September 6, 1928.

This invention relates to a fastener; and has for its object to provide a socket member having a head or cap ot a single piece ot material which is so shaped as to provide a broad, side edge and cause the same to have an appearance olf sulistantial thickn lith these and other objects in view, the inv ntion consists of certain novel leatures or' construction, as will be more fully described, and particularly pointed out in the appended claims.

ln the accompanying drawings:

Fig. 1 is a top plan view of the head or cap of the socket member of a fastener of the type which may be secured to a glove or the like.

Fig. 2 is a bottom view thereof.

Fig. 3 is an edge elevation.

Fig. t is a top plan view of the blank 'from which the cap is formed.

Fig. 5 is a side elevation of the blank drawn into cup shape.

Fig. 6 is a sectional view showing the head v or cap as secured to the itabric to which the socket member is attached by means ot a flanged stud receiving part. i

Figures 7 and 8 are respectively a top plan view of the blank for forming the stud receiving portion, and a sectional View ot' the completed stud receiving portion before it is locked into the cap.

It has been customary to make the front or cap portion oli' the socket member for a snap fastener, which is to have a thick edge, of two pieces off material, the foundation usually being of metal, with a thick celluloid covering folded about it by heat and pressure which molds it to form a broad edge or bead at sub stantially right angles to the general plane of the head and it is it'ound that this shape of button is preferable in the trade to one having a sharp edge formed by the bottom wall meeting the top wall at an angle, and in order to make the head or cap portion ot the socket member ol a single piece of material and yet obtain this broad edge etlect, I have formed the same from sheet stock cut and drawn in such a way as to make a distinct edge or bead on the button head and yet make the same out of a single piece ot material thus eliminating the two pieces oi" stock heretofore necessary flor obtaining this desired result; and the following is a detailed description ot the present embodiment et this invention il- Serial No. 304,251.

lustrating the preferred means by which these advantageous results may be accomplished:

vWith reference to the drawings, 1() designates a blank eut out to lorm projections 11 and notches 12 therebetween, which is drawn into the shape illustrated in Fig. 5 with a top plate 13 having a convex outer surlf'ace and a correspondingly concaved inner surface with a wall 14 extending therefrom cyliruilrically shaped at substantially right angles to the general plane of the top plate.

The wall 14 may be delined as a side wall, as it is ot' an extent to give breadth of edge surface or thickness to the head or cap oitl the socket member while the bottom formed by turning the projections 11 and a portion of the stock 12 from which they extend inwardly, which latter is to form a portion ol the bottom wall at substz'intially right angles to the wall 14C, as clearly illustrated in Fig. 3 and the projections 11 which are folded inwardly to form this bottom wall snugly abut each other, as illustrated in Fig. 2, to form a substantial unbroken bulging surface 1G with an opening 1T therethrough for the re ception ot' the stud-receiving portion 18 of the socket men'iber.

The edge of the blank is serrated to lessen the resistance on the tools which bend the metal inwardly. The material 19 to which the socket member oit the fastener is secured is clamped in position between the `flange 2O of the stud receiving part of this member as it is forced into position to spread and outwardly flare, its shank 21, as illustrated in Fig. 6, bending portions beneath the bottoni wall of the head or cap member to securely lock it in position and press the material 19 against the bulging port-ion 1G which is in a measure somewhat resilient to firmly hold the socket member in position on the material, the bulging portion orf the bottom also spacing the head or cap from the material which gives t0 the button a desirable appearance and iurther sets off the wide marginal edge thereof.

The stud-receiving portion 18 is formed of sheet stock blanked out as illustrated in Fig. 7, after which it is folded into substantially cup shape, as shown in Fig. 8, with a shank 21 and flanges 2O in which shape it is forced inwardly thru the opening 17. The closed end 22 of the shank engages the top plate and as pressure is applied the walls bend outwardly at the weakened notched points 23 shaping themselves as illustrated in Fig. 6, to securely lock the two parts of the socket member together.

It will be apparent that I have provided a structure by which a wide edge giving a desirable substantial thickness to the button is provided and yet the same is made in a single piece of sheet stock, which appearance in common practice has required two pieces of stock to produce.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

l. A snap fastener socket member cap formed of a single piece of material, comprisinga top plate, a side wall extending at substantially right angles therefrom aI substantial distance, and a bottom wall extending inwardly at substantially right angles to said side Wall and having al bulging middle portion with an opening therein for a studreceiving part, whereby said side wall forms a distinct bead.

2. A snap fastener socket member comprising a sheet material top plate, an integral side wall extending therefrom for a substantial distance at right angles to the material to which the member is to be attached, a bottom wall extending inwardly from said side wall at right angles thereto with a bulging middle portion having an opening therein, and a stud-receiving part in said opening flaring outwardly beneath said bottom wall and having a flange to engage one side of the material to which the member is fastened to hold the material firmly in engagement with the bulging portion of said bottom wall.

3. A snap fastener socket member comprising al sheet material top plate having an outer convex surface and an inner concaved surface, a cylindrical side wall extendingr therefrom for a substantial distance at right angles t the material to which the member is to be attached and at right angles to the general extent of the top plate, a bottom wall extending inwardly from said cylindrical side wall at right angles thereto with a bulging middle portion having an openin therein, and a stud-receiving part in sai opening flaring outwardly beneath said bottom wall and having a flange to engage one side of the material to which the member is fastened to hold the material firmly in engagement with the bulging portion of said bottom wall and space the cylindrical side wall therefrom.

4. A snap fastener socket member comprising a sheet material top plate, an integral side wall extending therefrom for a substantial distance at right angles to the material to which the member is to be attached, a bottom wall extending inwardly from said wall at right angles thereto with a bulging middle portion having an opening therein, and a stud-receiving part in said o ening, said studreceiving part having a c osed end and a shank weakened at a point t0 permit ontward bending beneath said bottom wall and a flange at the open end of the stud-receiving part to hold the material firmly in engagement with the bulging portion of the bottom wall.

In testimony whereof I affix my signature.
